The laser beam spot is the tool in laser welding cutting. Industrial lasers are really great,
but there's a huge problem when it comes to knowing the state of your tool. I mean, in a normal
milling machine the mill bit can visually be examined to see if a part of the edge is chipped
off. But how does your beam spot look? How is your beam quality? You might have pretty good
idea of how good the beam quality is but the truth is: You don't know. You can't just look at
the laser beam an tell. First of all trying to look at a laser beam without the right safety
measures could seriously harm you. Secondly, if you've got these measures in place, theres
nothing to see. Here's a guide on how you can build yourself a laser beam analyzer! Get going!
It's great fun!
